DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] For example, see Figures 1 to 5The utility model provides a filtering structure for sewage treatment, including a filter box 1, the surface of the filter box 1 is fixedly connected with a liquid inlet pipe 3 and a liquid discharge pipe 4, the end of the liquid inlet pipe 3 is fixedly connected with an inverted funnel 18, the inner wall of the filter box 1 is slidably connected with two filter racks 13, and the inner walls of the two filter racks 13 are distributed with coarse filter screens 12 and fine filter screens 11; auxiliary components for reciprocatingly moving the coarse filter screen 12 and the fine filter screen 11 are arranged in the filter box 1; cleaning components for cleaning impurities on the surfaces of the coarse filter screen 12 and the fine filter screen 11 are also arranged in the filter box 1; a control panel 2 is arranged on the surface of the filter box 1, and a fixing column is fixedly connected to the lower surface of the filter box 1.

[0027] More specifically, when this embodiment is used, Figure 1 , Figure 2 and Figure 3 As shown, the sewage pipe for conveying the sewage to be filtered is connected to the liquid inlet pipe 3, the sewage enters the filter box 1 through the liquid inlet pipe 3, and is filtered twice in the filter box 1 by the coarse filter 12 and the fine filter 11 in sequence.

[0028] Furthermore, the auxiliary component includes a motor 20 arranged on the upper surface of the filter box 1, the output shaft of the motor 20 is fixedly connected to a rotating rod 21, the surface of the rotating rod 21 is fixedly connected to a cam 22, and the surface of the filter frame 13 is fixedly connected to a semicircular block 26.

[0029] A limit block 27 is fixedly connected to the surface of the filter frame 13, and a rectangular slot 1 is provided on the inner wall of the filter box 1 for the limit block 27 to slide and fit into. A limit rod 28 is fixedly connected to the inner wall of the rectangular slot 1, and the limit rod 28 extends into the limit block 27 and is slidably connected thereto, and a spring 29 is provided between the limit block 27 and the inner wall of the rectangular slot 1.

[0030] like Figure 2 to Figure 5 As shown, the motor 20 is turned on. The motor 20 is a forward and reverse motor. As the motor 20 is turned on, the rotating rod 21 is driven to rotate back and forth, thereby causing the cam 22 to rotate back and forth. As the cam 22 rotates, when the end of the cam 22 away from the rotating rod 21 contacts the semicircular block 26, the filter rack 13 is pushed in the direction away from the cam 22, so that the coarse filter 12 and the fine filter 11 in the two filter racks 13 can be moved, and the spring 29 will also be compressed. When the end of the cam 22 away from the rotating rod 21 is separated from the semicircular block 26, under the action of the elastic potential energy of the spring 29, the two filter racks 13 can respectively drive the coarse filter 12 and the fine filter 11 to reset.

[0031] That is, as the motor 20 is turned on, the coarse filter 12 and the fine filter 11 can be reciprocated horizontally, so that the sewage falling from the inverted funnel 18 can be filtered more evenly, avoiding the problem of damage caused by excessive load on the filter directly below the inverted funnel 18, and avoiding the accumulation of impurities, thereby improving the filtering effect of sewage and also improving the service life of the coarse filter 12 and the fine filter 11.

[0035] The inner wall of the filter box 1 is slidably connected with a collecting box 6 , and a pull ring is provided on the surface of the collecting box 6 .

[0036] More specifically, when the present embodiment is used, after the filter box 1 has been used for a period of time, it is necessary to clean the impurities attached to the surface of the coarse filter 12 and the fine filter 11, such as Figure 3 and Figure 4 As shown, start the motor 2 9, and under the action of the pulley transmission mechanism 8, drive the threaded rod 1 and the threaded rod 2 7 to rotate, so that the two moving blocks 16 can respectively drive the two cleaning plates 17 to move on the surface of the coarse filter 12 and the fine filter 11, so that the impurities on the surface of the coarse filter 12 and the fine filter 11 can be pushed to the left side of the filter frame 13, so that the impurities fall into the collection box 6 below. There is no need to remove the coarse filter 12 and the fine filter 11 completely, and the cleaning work of the coarse filter 12 and the fine filter 11 can be automatically completed in the filter box 1. The operation is simple, the practicability is strong, and it is worthy of promotion and use.

[0037] Embodiment 3, based on the above embodiment,

[0038] Furthermore, in order to improve the filtering effect of the filter box 1 on sewage, a fixed plate 10 is fixedly installed on the inner wall of the filter box 1, and a stirring box 15 is fixedly connected to the lower surface of the fixed plate 10.

[0040] After the sewage in the mixing box 15 has reacted completely, the pump body 5 is turned on to discharge the filtered sewage from the drain pipe 4 .
